Consider the upgrade from 5800X to 7800X3D and evaluate its benefits.
Consider the upgrade from 5800X to 7800X3D and evaluate its benefits.
I'm considering a refresh for my gaming rig and need advice on whether to replace the CPU or not. I currently have a 5800X and am trying to decide its fate. Since I'm swapping out the case and power supply, essentially rebuilding the system, I'm looking at the bigger picture. My main goal is 4K gaming and it's connected to my TV. If I upgrade the CPU (and likely the other components too), I might be able to sell the whole setup on the used market. If not, I'll probably just sell my old GPU, which is still a bit of a dilemma. I'm leaning toward upgrading but want to avoid any performance gains. There seems to be more modern games that rely heavily on CPU power, though I'm unsure how much this upgrade would actually help. What are your thoughts?
No, I'm not experiencing any CPU limitations while playing games.
Right now, performance relies heavily on the GPU. Upgrading it will improve things soon.
I'll examine the games you're running to identify any CPU-related issues you might want to resolve. For instance, if you notice stutters or significant lag in multiplayer titles, a 7800x3D could likely fix it. If your focus is mainly on single-player RPGs, I'd skip the upgrade. For MMO or multiplayer games, 3D v-cache provides a worthwhile benefit.
Then dismiss it. 5800X can handle most GPUs at 4K, 4K is quite limited for GPUs these days. If you really want to upgrade, consider Ryzen 7 7700 or Core i7 13700. Unless you're playing heavily cache-intensive games like Assetto Corsa Competizione, the gap won't be noticeable.
I believe the answer still hinges on the particular games in question. Whether 4K is supported or not, MMO/multiplayer titles remain single-threaded, often causing sub-60 fps drops without additional L3 cache. Intel's 13th generation chip includes significant cache to offset this. In the mostly optimized, multi-threaded games that benchmarkers rely on? 4K performance stays GPU-dependent, making it less likely to be affected. Even with a huge gap between a 4790k and 7950x3D—ranging from similar frame rates to a 2.6x jump at 4K ultra—the numbers are more intuitive for players, as I crafted each example to showcase different scenarios involving CPU, GPU, or engine constraints.
I was trying to skip the PC disassembly process, then rebuild it with upgraded components if needed. If performance didn’t meet expectations, I’d extract the CPU, RAM, storage, and cooling parts from the old system and reinstall them in the new build. My main concern was the impact of UE4 games that run on just a few cores, causing noticeable stuttering. I’ve reviewed those videos and several benchmarks, but I’m unsure benchmarks fully capture the issue since they’re often limited to specific titles. The biggest worry was seeing people experience frequent stuttering in poorly optimized games where most activity runs on a single core.
For a X3D you can use a 5800X3D, it should work well on any board that has the 5800X. Switching platforms for a one-generation upgrade isn't worth it in my opinion. If you have an older Zen or Zen 2 and an older board, go ahead. The decision depends on your budget and personal choice.
I occasionally do testing between CCD0 and CCD1, effectively running a 7800x3D or 7700 by down configuring my 7950x3D and there's a noticeable smoothness difference even between those two. 3D v-cache in itself is practically the only thing keep AMD up with Intel in single threaded performance, but that may change if Intel starts increasing the L1-3 cache even more drastically in their CPUs. Intel could make a special batch of their latest architecture that gets rid of the E cores and just levies a larger portion of the die to the L3 cache/ringbus, more so than what they're already doing with 13th gen. They could call it a G series, and I'd likely buy the hell out of that. For reference. They could just make the shared L3 cache thicker, and levie the edges of the die for P cores. Maybe even just take the same area per P core and rotate it, then get either 2/4 or all 4/4 of the E core clusters' die space for more L3 cache.
